GE Vernova (NYSE: GEV) has announced the start of commercial operations at the Goi Thermal Power Station in Chiba Prefecture, part of the Greater Tokyo Area, following the installation of Japan’s first 9HA.02 gas turbines. The project adds over 2.3 gigawatts (GW) of capacity—equivalent to the power needs of approximately 2.2% of Japanese households.

The facility is operated by Goi United Generation (GIUG), a joint venture between JERA, ENEOS Power, and Kyushu Electric Power. The power plant replaces a 1960s-era facility that was retired in 2018 and marks one of Japan’s largest LNG-fired power plants.

In addition to three 9HA.02 gas turbines, GE Vernova supplied three Heat Recovery Steam Generators (HRSGs). These were prefabricated in South Korea—each in the form of three Supermodules, each weighing around 2,500 metric tons and reaching heights of up to 46 meters. The modules were transported to Japan under tight spatial and logistical constraints.

The plant is expected to reduce CO₂ emissions by around 16% compared to the original facility, contributing to Japan’s energy transition goals.

“This project ensures a reliable electricity supply while advancing decarbonization,” said Mr. Sato, CEO of Goi United Generation.

GE Vernova collaborated with Toshiba on integration, continuing their over 100-year partnership in Japan’s energy sector.
